Application filed May 20, 1919. Serial No. 298,456.

To all whom it may concern:

Be it known that we,.PERrEoTo M. ELIAS and FELIX F. LLERA, citizens of the United States, residing at Tucson, in the county of Pima and State of Arizona, have invented new and useful Improvements in Soldering and Melting Apparatus, of which the following is a specification. v

The general object of our present invention is the provision of a soldering and melting apparatus of blow-pipe type, designed more particularly for jewelers use, and constructed in such manner that it is unnecessary for the operator to pay any attention to the connection between the gasoline receptacle and the source of compressed air sup- 1 p I n the practical use of our novel apparatus it is simply necessary for the operator to manipulate a single valve in order to regulate the flame afforded.

With the foregoing in mind the invention in all of its details will be fully understood from the following description and claim when the same are read in connection with the accompanying drawings, hereby made a part hereof, in which:

Figure 1 is a view partly in side elevation and partly in section, of our novel apparatus as a whole.

Fig. 2 is an enlarged detail longitudinal section illustrative of the blow-pipe and its appurtenances.

Fig. 3 is a detail View illustrative of a modification hereinafter explicitly referred to.

Similar numerals designate corresponding parts in Figs. 1 and 2, to which reference will first be had:

The gasolenecontainer 1 shown in Fig. 1 may be and preferably is of glass. Said container, however, may be formed of metal, in which event the container numbered 1 in Fig. 3, will be provided with a filling conduit 2 let into the side thereof and provided with a suitable closure 3. This filling provision assures the container being filled to the height indicated but no higher, as is desirable.

In the embodiment shown in Fig. 1, the

filling or partial filling of the gasolene container 1 is effected through an opening 4 norhead 11 or the apertures mentioned of sediment collected therein.

By comparison of Figs. 1 and 2, the blowpipe member of our improvement will be readily understood as comprising a blowpipe 13, the heel end of which is connected with aconduit 7 through the'medium of a flexible tube 14. In addition to the pipe 13, the blow-pipe member comprises a supplemental tube 15 arranged in substantially parallelism to the pipe 13 and joined thereto through the medium of a bracket 16 and a tube section 17. At its forward end the supplemental tube 15 is provided with a lateral arm 18, and on said arm is screwed or otherwise attached a head 19 in which is an annular foraminous diaphragm 20. The blowpipe 13 is preferably tapered as shown, to ward its discharge end, and is provided with an arm 21 that extends through the arm 18 of the tube 15 and has its discharge endor nozzle 22 disposed in the annular diaphragm 20, as illustrated. The rear end portion of the supplemental tube 15 is carried in rear of the conduit section 17 and is interiorly shouldered as indicated by 23, to form a seat for the flange 24 of a valve 25, Which valve has an angular bore 26. On the valve 25 is a stem 27 that extends loosely through a cap 28, threaded on the rear end of the tube 15. Surrounding the stem 27 and interposed between the valve 25 and the cap 28 is a coiled spring 29. which has for its function to tightlv hold the flange 24 against the seat 23. In rear of the can 28, the stem 27 is provided with a knurled head 30 through which the valve 25 may be turned about its axis to establish or interrupt connection between the pipe 13 and the supplemental tube 15. The said head 30 is sleeved on the stem 27, and is keved thereto bv a pin 31 which serves the additional function of a pointer, inasmuch as it indicates when directed toward the pipe 13 that the valve is open.

In the'p'ractical operation of our apparatus it will be observed that the commingled gasolene and compressed air are discharged from the container 1 through the blow-pipe 13; and it will also be observed that incidental to the use of the apparatus, the operator has only the valve 25 to manipulate, and through the medium of the said valve 25 he can expeditiously and easily establish or interrupt connection between the conduit section 17 and the rear portion of the supplemental tube 15.

WVe have entered into a detailed description of the construction herein shown, inasmuch as said construction constitutes the best practical embodiment of our invention of which We are cognizant. lVe do not desire, however, to be understood as confining, ourselves to the specific construction and relative arrangement of parts, inasmuch as in the future practice of the invention changes in the form and zrrangement of parts may be made Within the scope of our invention as defined by our appended claim.

Having described our invention, What We claim and desire to secure by Letters-Patcut, is: 7

An apparatus for the purpose described,

comprising a hydro-carbon container, means whereby the interior of said container may be connected With a source of fluid pressure supply, a blow-pipe connected with the interior of the container, a supplemental tube arranged in fixed relation to the blow-pipe and having a head and a fora-minous diaphragm therein receiving the discharge end of the blow-pipe and also having a valve casing in its rear portion, a conduit section connecting intermediate points of the blowpipe and valve casing, a valve arranged to be turned about its axis in said casing and having an angular bore and a flange, the latter to seat in the casing and also having a stem, a cap secured on the rear end of the valve casing and loosely receiving said stem, a spring surrounding the stem and interposed between the valve and said cap, a head, sleeved on the stem in rear of said cap, and a pin through which the sleeve of the head is keyed to the stem; said pin being adagiited to servethe' additional function of a pointer.
